Now, for what you're looking for, the websites that have us flocking to sign up and make lots of money. Depending on where in this fine world you live, these sites pertain more to residents of the U.S. but some offer International options for those who are not.
Focus Line- This site does have a higher payout threshold of $25, but it really doesn't take that long to meet it. You get a few offers per day to try and qualify for and the money does add up quickly. Be sure to have a PayPal account, because they don't send out checks!
Palm Research - Not your typical online survey website site. What this site is, is a survey portal, meaning they draw surveys from numerous other survey websites and link them to their website. These surveys only pay cash, $1 on average, and you get many chances to qualify. You only need $10 to cash out and once you do, you'll be paid 45 days after the end of the month you get there. This site also pays by Paypal and they do it quickly.
Opinion Outpost- Maybe not the best of the good sites, but it's up there. They have a low payout of $5 and they send a lot of surveys your way. They're very strict about users following their guidelines and won't hesitate to disable an account, so read up and make sure you know what not to do.
The next list of sites are considered bad. Not quite bad enough to completely cast off, but good enough to at least try out for a bit. Whether you want to sign up is your decision, as some have better luck than others.
Socratic Forum - It seems like they only send out one or two surveys a month and they're usually looking for distinct characteristics to meet their quota that many people don't match. Their surveys usually pay $3, sometimes $5, and you can cash out for a check once you hit $10. It takes a very long time to get your check in the mail, however, so don't cash out if you really need their money for something important.
GlobalTestMarket - They used to be better but recently opted to start offering many sweepstake entry only surveys. They have a high cashout for 1000 points, or $50, and takes a long time to reach it. If you get on a roll with them, though, the points will add up quick.
Lightspeed Panel - The average survey pays 75 points and you need at least 525 to get a $5 Paypal cashout. If you have a technical error with their surveys, happens more often than other sites, don't expect any reply from customer service.
And lastly, the ugly bunch. These sites usually are regarded as the bottom of the barrel as far as many survey takers are concerned.
TestSpin - They send out tons of surveys every month but don't count on qualifying for very many. There are also a good portion they don't give you credit for if you do. Customer service is also non-existent.
Toluna - Wow! This site had always been a little rigid in qualifying for their surveys, but since they merged with Greenfieldonline and went to a point system with an extremely high cashout, it's almost impossible to qualify.
Survey Savvy - I'm not even sure they still send out surveys anymore, but their site is still active. Who knows...
Take each of these submissions with a grain of salt as they are but one person's opinion.
Feel free to try each and all out for yourself and make up your mind as to what is good, bad and ugly.
